[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] A tension positioning structure for a downlight includes a lamp body 1 and a mounting cylinder 2. The top of the lamp body 1 is connected to an adjusting seat 5 via a gooseneck tube 4. The lamp body 1 and the adjusting seat 5 are slidably installed inside the mounting cylinder 2. Mounting clamps 11 are rotatably installed on the outer walls of both sides of the mounting cylinder 2. The wires of the lamp body 1 pass through the inside of the gooseneck tube 4. The adjusting seat 5 has a wire groove for the wires of the lamp body 1 to pass through.

[0028] The lamp body 1 is mainly responsible for lighting. The lamp body 1 can achieve multi-angle light adjustment through the gooseneck tube 4 at the top to meet the key lighting needs of different scenes. The adjustment seat 5 is connected to the lamp body 1. The spring positioning beads 6 on both sides of the adjustment seat 5 can cooperate with the positioning groove 7 on the inner wall of the mounting cylinder 2 to fix the position of the lamp body 1 after it is stretched. The mounting cylinder 2 serves as the support and installation carrier of the overall structure. It provides sliding space for the lamp body 1 and the adjustment seat 5. The limiting groove 9 at the bottom cooperates with the folding adjustment plate 3 to make it easy to pull out the lamp body 1. The mounting clamp 11 on the outer wall of the adjustment seat 5 can also be used to embed and fix the entire downlight device in the ceiling or other installation positions.

[0029] It also includes a positioning component, which includes a spring positioning bead 6. The spring positioning bead 6 is installed on both sides of the adjusting seat 5. Multiple positioning grooves 7 that cooperate with the spring positioning bead 6 are equally spaced inside the mounting cylinder 2. Limiting blocks are fixedly installed on the other two sides of the adjusting seat 5. Guide grooves that slide with the limiting blocks are provided on the inner wall of the mounting cylinder 2.

[0030] The positioning component is designed to fix the position of the lamp body 1 after stretching and adjustment. When the lamp body 1 moves the adjusting seat 5 to the target position within the mounting cylinder 2, the spring positioning bead 6 automatically engages with the corresponding positioning groove 7, thus fixing the position of the lamp body 1 after stretching. This effectively prevents the lamp body 1 from shifting or shaking during use, significantly improving the installation stability and lighting reliability of the downlight. At the same time, the sliding cooperation between the limiting block on the adjusting seat 5 and the guide groove on the inner wall of the mounting cylinder 2 further constrains the movement trajectory of the adjusting seat 5, preventing the adjusting seat 5 from rotating or shifting, and ensuring the precise cooperation of the positioning component and the smooth adjustment of the lamp body 1.

[0031] It also includes a folding adjustment plate 3, which is slidably installed on both sides of the bottom of the mounting cylinder 2. The folding adjustment plate 3 includes a pull block 301, which works in conjunction with a hook plate 8. The hook plate 8 is fixedly installed on both sides of the bottom of the lamp body 1. The bottom of the pull block 301 abuts against the top of the hook plate 8. The pull block 301 is fixedly installed on one side of the top of the connecting plate 302. A limiting groove 9 is provided on the inner wall of the bottom of the mounting cylinder 2. The limiting groove 9 slides in conjunction with the connecting plate 302 and the pull block 301. The limiting groove 9 has a T-shaped cross-section. The connecting plate 302 is restricted to its interior only by the limiting groove 9. The connecting plate 302 slides up and down. An anti-detachment block is integrally formed on the other side of the top of the connecting plate 302. The anti-detachment block slides and engages with the anti-detachment groove inside the limiting groove 9. The bottom of the connecting plate 302 is rotatably connected to one end of the pull plate 304 through the hinge 303. The pull plate 304 slides and engages with the limiting groove 9. Anti-slip grooves 305 are formed on both sides of the pull plate 304. A buckle groove 306 is formed on the other end of the pull plate 304. A locking block 307 is integrally formed on both sides of the buckle groove 306. The locking block 307 is engaged in the locking groove 10. The locking groove 10 is formed on the inner wall of the limiting groove 9.

[0032] The main function of the folding adjustment plate 3 is to enable convenient stretching and adjustment of the lamp body 1. The folding adjustment plate 3 cooperates with the hook plate 8 at the bottom of the lamp body 1 through the pull block 301. When it is necessary to pull out the lamp body 1 embedded in the mounting cylinder 2, the pull plate 304 hidden in the limiting groove 9 can be flipped out through the buckle groove 306. By simultaneously pinching the pull plate 304 with both hands and pulling the pull plate 304, the pull block 301 can be moved down through the connecting plate 302, and then the lamp body 1 can be pulled down with the help of the hook plate 8. No additional tools are needed, which avoids scratching the outer wall of the lamp body 1. After the adjustment is completed, the pull plate 304 can be pushed up and rotated and folded along the hinge 303 and stored in the limiting groove 9. The storage and fixation are achieved by the snap-fit ​​cooperation between the locking block 307 and the snap-fit ​​groove 10, so that the pull plate 304 and the mounting cylinder 2 remain flat and integrated, which does not affect the embedded aesthetics of the downlight and prevents the pull plate 304 from being exposed and damaged by bumps.

[0033] In practical use, when moving this device to the designated position, first rotate the mounting clamp 11 upwards, pass the mounting cylinder 2 and mounting clamp 11 through the preset mounting hole, and after installation, the torsion spring pushes the mounting clamp 11 downwards to clamp the four sides of the mounting hole, achieving stable installation; when it is necessary to adjust the extension length of the lamp body 1 to adapt to the lighting needs, the pull plate 304 hidden in the bottom limiting groove 9 of the mounting cylinder 2 can be flipped outwards through the buckle groove 306 at the end of the pull plate 304, and the pull plate 304 can be pinched with the anti-slip grooves 305 on both sides of the pull plate 304 and pulled downwards. The pull plate 304 drives the pull block 301 to move downwards synchronously through the connecting plate 302. The pull block 301 cooperates with the hook plate 8 at the bottom of the lamp body 1 to pull the lamp body 1 and the adjusting seat 5 to slide smoothly along the inner wall of the mounting cylinder 2. During the process, the spring positioning beads 6 on both sides of the adjusting seat 5 will continuously move with the mounting plate 304. The positioning groove 7 on the inner wall of the cylinder 2 engages and disengages. After the lamp body 1 extends to the target length, the spring positioning bead 6 automatically engages with the corresponding positioning groove 7 to achieve stable fixation of the lamp body 1. At this time, the angle of the lamp body 1 can be adjusted by the gooseneck tube 4 at the top of the lamp body 1 to accurately focus the light. Finally, the pull plate 304 is pushed upward and folded along the hinge 303 back into the limiting groove 9. The locking blocks 307 on both sides of the pull plate 304 latching groove 306 engage with the locking groove 10 on the inner wall of the limiting groove 9 to complete the storage of the folding adjustment plate 3, so that the device maintains a flat and beautiful embedded state. When it is necessary to retract the lamp body 1 or adjust it to a shorter extension length, simply hold the lamp body 1 and push it upward. The spring positioning bead 6 is compressed and retracts, disengaging from the positioning groove 7. After the lamp body 1 moves upward with the adjustment seat 5 to the target position, it is fixed by engaging with the positioning groove 7 again through the positioning bead.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
